Problems solved by technology

However, the conventional air-bath vaporizer uses outdoor air as the heat source. Due to the unstable temperature and flow rate of the outdoor air, the heat exchange effect is unstable and poor. Further worsen the heat exchange effect, making it difficult to provide sufficient gas demand

Abstract

The invention discloses a waste heat recycling type cooling water system. The waste heat recycling type cooling water system comprises a cold insulating water tank as well as a water supplementing tube, a hot water tube, a cold water tube and a water exhaust tube which separately communicate with the cold insulating water tank, wherein the cold insulating water tank comprises a cold insulating layer packaged on the cold insulating water tank, a coiled tube arranged in the cold insulating water tank, a gas tube which communicates with the upper end of the coiled tube, a liquid tube which communicates with the lower end of the coiled tube, a supplied water collecting tube arranged on the bottom of the cold insulating water tank and a returned water distributing tube arranged on the top of the cold insulating water tank; a row of uniformly distributed small holes is formed in the upper half circular part of a pipeline of the supplied water collecting tube; the supplied water collecting tube communicates with one end of the cold water tube; a row of uniformly distributed small holes is formed in the lower half circular part of a pipeline of the returned water distributing tube; and thereturned water distributing tube communicates with one end of the hot water tube. The waste heat recycling type cooling water system disclosed by the invention can improve gasifying heat exchange effect and stability of liquefied gas.

Description

technical field [0001] The invention relates to a waste heat recovery type cooling water system, which can be used for the cooling water supply and return water of various factory buildings and civil building processes or chillers for air conditioning, and belongs to the technical field of cooling. Background technique [0002] The cooling water on the condenser side of the chiller is generally provided by the cooling tower. The conventionally designed cooling tower generally adopts an outdoor open cooling tower, and the cooling water return temperature of the cooling tower is generally 37°C. Since the heat grade of the return water is not high, It is difficult to be used, and the heat is generally lost directly to the atmosphere through air cooling. On the other hand, through air cooling, the floating water rate is high, and the cooling water replenishment consumes a lot of water, which is neither energy-saving nor water-saving. [0003] In addition, the bulk gas used in f...
